Estimation of genetic parameters for a new model for defining body structure scores (frame scores) in Nellore cattle

A. R. V. R. Horimoto, Ferraz, J. B. S., Balieiro, J. C. C., and Eler, J. P., Estimation of genetic parameters for a new model for defining body structure scores (frame scores) in Nellore cattle, vol. 5, pp. 828-836, 2006.

Models for estimation of frame scores in Nellore beef cattle (FRAME_GMA) were developed, comparing them with frame scores estimated using equations proposed by the Beef Improvement Federation (FRAME_BIF, USA). Correlation among frame scores obtained by these two methodologies, along with the independent variables considered in the estimation models, were also studied. A data set with 12,728 animals, with ages between 490 and 610 days, was used. The models that best adjusted to FRAME_GMA included hip height, weight and interaction between height and weight.
